ROOF MOSS MAINTENANCE

Roof Moss Maintenance Victoria BC for Ongoing Roof Protection

One moss treatment keeps your Victoria roof clean for 1–2 years, but the real protection and savings come from staying on the program.

Thomson's Roof Moss Maintenance Program allows us to track your warranty expiry and schedule your retreatment before moss ever takes hold again. No chasing quotes every two years. No letting moss re-root because life got busy. Just a permanently protected roof, maintained by the same team Victoria has trusted since 1984.

Why regular moss maintenance
protects the life of your roof

Moss doesn't stop when your treatment expires. It starts re-establishing within weeks of the guarantee period ending if left untreated. In Victoria's Pacific climate, that re-growth cycle is faster than most homeowners expect.

Here's what Thomson's data from 40+ years of roof maintenance shows:

  • A roof retreated on a schedule (every 1–2 years) stays in significantly better structural condition than one allowed to moss up between treatments.
  • Retreatment on a clean, well-maintained roof takes less time and costs less than retreating a roof that's been left to re-establish moss.
  • Clients who stay on the Maintenance Program consistently report that their roofs look newer and last longer than neighbouring homes of the same age.

The Thomson Maintenance Program

1. Initial Treatment: We remove visible moss by hand, clear gutters, apply our non-toxic solution, and issue a written 1–2 year guarantee.

2. Warranty Tracking: We keep your property on file and contact you when your next retreatment window approaches.

3. Retreatment: Future care is faster, simpler, and more affordable than the initial removal, renewing your 1–2 year guarantee.

4. Repeat Indefinitely: Long-term maintenance keeps your roof looking new and pays for itself by avoiding costly roof replacements.
MOSS PREVENTION

What happens if you delay retreatment?

Roofs must be re-treated promptly at the end of the warranty period to avoid allowing moss to re-root and grow. Although it may be convenient or seem financially prudent to delay re-treatment, we have found that the monthly cost to maintain your roof remains constant, regardless of when re-treatment is done, the only change is the potential damage that is done to your roof when moss is allowed to continue to take root.

Over ten years of proper maintenance, a roof maintained regularly by Thomson Roof Treatment will avoid damage caused by moss re-growth.
FAQ

Frequently Asked Questions

In Greater Victoria's climate, roofs typically need retreatment every 1–2 years. Thomson assesses each roof individually and issues the most generous warranty the condition supports.

No. Thomson tracks your property and contacts you when your retreatment window is approaching. You don't need to manage the schedule.

Moss re-roots quickly in the local climate. Once established, it holds moisture against the shingles and accelerates granule loss and rot. The next removal requires more preparation time, which increases the cost. Staying on schedule avoids these issues.
